Energy Saving,Environmental Protection:Top Priority in China's Development——Exclusive interview with Dr.Yonglong L,Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).

Energy saving,emission reduction and economic development are major issues China has to meet in building a harmonious society.On one hand,China should pursue a sustainable,fast and sound economic development,on the other hand,she should try to decrease the overuse of energy resources and the environ- mental problems caused by the rapid economic growth. In this regard,on June 24,the Standing Committee of National People's Congress deliberated the draft of Energy Saving Law,according to which China is to take"resources saving"as a basic national policy.This is a key issue to the long-term benefits of China.With relevant questions,China's Foreign Trade interviewed Dr, Yonglong L(?),Secretary-general,Chinese Committee for SCOPE(Scientific Committee on Problems of the Environment/ICSU).and Research Professor at the Chinese Academy of Sciences. Let's listen to Dr.L(?)'s comments with wisdom.

Water resources optimization and eco-environmental protection in Qaidam Basin

In order to realize sustainable development of the arid area of Northwest China, rational water resources exploitation and optimization are primary prerequisites. Based on the essential principle of sustainable development, this paper puts forward a general idea on water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources optimization. By some qualitative methods such as Input-output Model & AHP Model and some quantitative methods such as System Dynamics Model & Produce Function Model, some standard plans of water resources optimization come into being. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.

The Brief Introduction to the Sino-US Joint Centers for Soil and Water Conservation and Environmental Protection

Erosion and transport of soil has worldwide implications for agriculture, landscape stability, climate, natural hazards, and clean, renewable resources of water and air. Assured access to clean water and a healthy and safe environment requires an ethic of conservation and protection. The minimum scale in which these principles apply successfully is basin wide. These are the fundamental concerns of the Sino-US Centers for Soil and Water Conservation and Environmental Protection.

The Low-Carbon and Environmental Protection of Textile and Garment in China

It should be transformed from the extensive development in the past to the new normal form of environmentally friendly pattern of “save energy, lower consumption and less pollution” in the Textile and Garment. For the pollution problem in China’s textile and garment industry, the author particularly analyzes the pollution of the textile and garment industry mainly occurred in the process of textile and clothing production and sales in this article. Finally, the author puts forward detail measure to control the pollution from the two aspects and advocates the concept of low-carbon environmental protection and green lifestyle. The low-carbon environmental protection has become a phenomenon in Textile and Apparel.

Environmental Protection of Biodiversity in Macedonia and Albania under Legal Analysis View

Environmental problems in the Republic of Macedonia and Albania are similar in other countries in the region. Numerous problems and deficiencies identified through different projects. The studies and planning documents are evident for environmental media and areas. Such as lack of regional integrated systems for municipal solid waste management. The system for special waste types management, including hazardous waste, insufficient coverage of populated places and municipalities by wastewater collection and treatment systems （especially in agglomerations above 10,000 populations）. The need to establish integrated river basin management is in accordance with the new law on waters, air pollution with different intensity in different parts of the country. This paper presents the imperative reforms to protect the natural resources and biodiversity in the countries.

Combination of drainage, water supply and environmental protection as well as rational distribution of water resource in Zhengzhou mining district

The geological condition of coalfield is much complex in China. With increasing in mining depth and drainage amount, the contradiction of drainage, water supply and environ-mental protection is becoming more and more serious. However, the contradiction can be solved by the scientific management of optimizing combination of drainage, water supply and environ-mental protection. The Philip multiple objectives simplex method used in this article has searched for a possible solution at the first step, and then it goes on searching to find out whether there is a weight number that can lead the solution to the biggest. It can reduce the randomness and diffi-culty of traditional weight method which determine the weight number artificially. Some beneficial coefficients are vague and the number is larger in the model of water resource dispatch. So the vague layer analysis method can consider these vague factors fully, combining the qualitative and quantitative analysis together. Especially, this method can quantify the experiential judge-ment of policy decider, and it will turn to be more suitable if the structure of objective factors is complex or the necessary data are absent. In the paper, the two methods above are used to solve the plans of drainage, water supply and optimizing distribution of water resource in the Zhengzhou mining district.

Study on Regulating Effects of "Aquatic Environment Protection Oriented Fishery" on Water Environment of Qiaodun Reservoir

In order to evaluate the regulating effect of ＂ aquatic environment protection oriented fishery＂ on aquatic ecosystem,the water quality,plankton community structure,biomass,diversity index,eutrophication index and ecosystem maturity evaluated with Ecopath model were compared from 2010 to 2012 in Qiaodun Reservoir of Zhejiang Province. It was indicated that the water quality had been improved obviously. The water transparency maximally increased by 130%,while TP,TN and CODCrwere reduced. The density and biomass of the plankton were decreased,so was the ratio of Cynobacteria in phytoplankton community. The Shannon-Weaver index was increased; the trophic level was decreased; the ecosystem maturity was improved. By all accounts,the ＂ aquatic environment protection oriented fishery＂ had positive effects on maintaining the balance of reservoir ecosystem and ensuring the safety of drinking water.

Research on degradation of 2, 4 dichlorophenol and pentachlorophenol in water by electron beam irradiation

Electron beam was successfully used for the degradation of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) in water. The effects of radiation doses on substrate degradation and dechlorination of solutions with concentrations of 50 mg/L for both chlorophenols were investigated. The effects of initial concentration, pH and absence of oxygen on the degradation were also investigated. The concentrations of 2,4-DCP and PCP remaining in solution after irradiation were measured by high-performance liquid chromatograph (HPLC). The results showed that an increased radiation dose led to increased degradation of the chlorophenols and increased Cl- yields. In all cases, the rate of degradation was found to be higher than the corresponding inorganic chloride yield from the parent compound. Deoxygenation was also found to increase the rate of degradation of the chlorophenols in water while degradation under alkaline condition was lower than at low to neutral pH.
